Thanks, for some reason I assumed the BIOSes are model-specific.
The thinkwiki page just links to an older version of the modded BIOS.

This thread comes up on the first page in "x220 7260" google search, so I'm reviving it to post my own experience in here. I have an X220 that originally came with Intel 6250 wi-fi card and a Bluetooth 2.0 Daughter Card. First I've bought a Bluetooth 4.0 Daughter Card (for X240), it worked fine afte...

I've updated to the modded version of 1.43, obtained from bios-mods (google for: x220 ValdikSS 1.43).
No visible changes or problems so far.

Deal. :) I noticed your profile says you are from Russia. Would you be able to recommend a shop that ships overseas? I need an X220 keyboard with Cyrillic layout, shipped to Romania. If you happen to know a reliable place, please let me know. Thanks in advance! I'll reply by PM to avoid flooding he...

Yes, due to the timings. I wouldn't worry too much about it! Same as I will not worry about my RAM working at 1600 rather than 1866 MHz. Deal?

Agree on SiSoft interface! It's `Memory Controller > Cache & Memory Latency`. Thanks for the HDD link. I'm considering getting a new Samsung 850 series mSATA SSD + a big HDD like yours. I was sure to disable sparse files in uTorrent when I was tweaking it's options the other day. For some reason, af...

Yeah, that's the first test I ran. Basically raw speed (sequential access) of the RAM. My result is 20.0 GB/s, yours is just slightly better. How about memory latency test? It's related to both frequency and timings, and basically tells you how fast is random access of the RAM. Here's an awesome pos...

Thanks. But $96 for slightly faster memory? Somehow I doubt this would be justified. Am I wrong? Even if it was $10 it wouldn't be justified. Memory speed upgrades is one of the most useless ones, that's almost never felt outside of benchmarks. I was suspecting as such. Thanks (especially from my wi...

Long-time lurker, first-time poster. Greetings! I was using the original 1.42 BIOS, just updated to this modified version, didn't change any of the BIOS settings yet. One thing I noticed (albeit not immediately) that suddenly I can't use Fn-F4 or Start > Sleep (Windows 7 x64), that's quite unexpecte...
